Finn: Son of Mace Windu, grandson, or, some sort of nephew? Hopefully a grandson, that way we may eventually get some stories of how he survived the fall and what he did before siring Finn sometime after the destruction of the second death star.
Rey: It's almost too obvious that she's Han and Leia's daughter so I'm halfway expecting a curve to be thrown (nah.)
Kylo Ren: Pretty sure we have another set of twins on our hands here.
First scene: A first order Star destroyer slowly crawls by. Illustrating how things have changed, it's being pursued by an even more massive resistance cruiser. After a huge explosion, it crashes into the waters of Naboo instantly killing all underwater life (especially the gungans.) Unfortunately, every Ewok from the forest moon of Endor was currently visiting the Gungans and also died in the explosion.
